Ambulatory legs (P2-P3). - Dorsolateral margins of P3 propodi rounded. Dactyl of P3 subequal to propodus or slightly shorter. Distal pilosity of P3 more prononced than on distal P2, but not forming a dense brush of setae. Ventral margin of P3 dactyl with less than 10 spines.

Armament of telson. - Left lobe of telson with several spines disposed on posterior margin only. Right lobe with several spines.

Coloration. - Shield purple-brown ('red with tinge of purple'). Ocular peduncle multicolored with narrow ring close to cornea. Detailed coloration of ocular peduncle: proximally pink, grading to pale pink or white distally. Chela uniformly colored, often grading to paler distally ('Chelipeds purple, fingers white'). Ambulatory legs (P2 & P3) with ring(s) (Orange, dactyl cream-colored, except for dark red band proximally).
